摘要:

积极推进土地利用转型潜力及其评价研究,是丰富和完善土地利用转型理论的重要途径。通过拓展土地利用潜力概念,对土地利用转型潜力定义、内涵、形成机制与评价的理论框架进行了探讨。研究认为,① 作为土地利用及LUCC的结果,土地利用转型具有土地利用形态“变化”和“可调控”的重要特征,这是土地利用转型潜力形成与释放的前提;② 土地利用转型潜力是指为适应区域发展综合需求,通过采用相应技术、政策等手段,在特定转型阶段所能实现最优土地利用形态与土地利用形态现状的差异;③ 土地利用转型潜力以基于“强效”“快速”政策调整及工程技术措施的土地利用形态调整和基于“自发土地利用”的土地利用转型引导为形成机制;④ 应以系统论和动态视角为基础,通过分析土地利用转型过程与机理,构建基于土地利用转型情景模拟的土地利用转型潜力评价理论框架。研究取得的成果和结论具备进一步激发土地利用转型理论研究及其在土地管理决策等方面积极作用的价值。

Abstract:

It is essential to promote efforts on land use transition to carry out definition, theories and approaches for land use transition potential estimation. This paper made a systematic review on land use, land use and cover change (LUCC), land use transition and their interactions. Discussion mainly focused on the definition, and connotation and creation mechanisms of land use transition potential was then claimed based on the expanded land use capacity. Further, this work developed a theoretical framework for estimating land use transition potential by land use transition modelling with land use benefits as driving forces, and resource and environment carrying capacity as restricting factors. It is declared that, (1) land use transition, as the outcome of land use, obtained the characteristic, namely changing and controlling land use morphology, provided primaries materials for promoting land use transition potential. (2) Land use transition potential refers to the differences between the current land use morphology and optimal one derived in special land use transition adjusted by certain policies and techniques following the regional development goals from a long-term perspective. Obviously, land use transition potential is virtually an expansion and further definition of land use capacity. (3) Land use transition potential could be made by adjusting the land use morphology using policies and techniques that are usually efficient and competent dealing with this issue. And it can also be promoted by the initiatives concerning guidance for land use transition. They compose the framework for land use transition potential estimation. (4) Moreover, it can make full use of the mechanisms of land use transition to model land use transition and thus determine the land use potential from a dynamic perspective. In the study, the framework was developed based on land use transition modelling taking into account driving mechanisms by land use transition benefits and restrictions by resources and environmental carrying capacity. Though issues especially including approaches for optimizing land use transition patterns, reconstruction and models for land use transition mechanisms under different management scenarios remain a challenge for use, results and conclusions derived from this study may promote researches on land use transition theory and its applications in land-use management decisions.
